Can someone please explain why when I selected 680 "Enrolled" students to archive their final reports, PCR Educator showed that 695 reports are being archived?

When reports are archived, they are archived for each household that is connected to a student and has the “send mail” option checked. If you have students that are linked to more than one household with the “send mail” option checked, then it is expected by design that more reports will be generated than the number of students that were selected.
